Vand advancingt'hegsame as needed, such asin n Enis'm is supportedv'on apivoted lever 24 havinga handle part 25 for operating the lever aboutits pivotal axis. Preferably'the handle part 25 is in the form of achannel havinga back web and sideribs, the back web extending only ashort distance to make the lever cof-a rigid construction leaving theside rib extensions to constitute the greater part ofy thelever. 10

These side ribsare pivoted to the member 9 at the sides of the opening23-by .means of ya piny2-positioned slightlybelow thealigned bore inthe'tube 7 and bushing14.

A vlinkage-.27 preferably in theformvof av channel having a back web andside ribs, is vpivotally connected tothe end of 'th'elever 24, oppositefromfthe handle end 25, by means of a pivot pin'28E extendingthroughrthe side ribs of the lever 24 andtheside ribs of the link member27.

Anapertu're 41' is provided'adjacent theV endofthe arm 39 of'a slightly greater'diameter than the widthy of'the'strip 8.V The material strip 8 is extended through theapertur'e 22of the nut` 18 andfbushing 14 intolthe rectangularopening 23 lformedinthe member .9, hence through the two apertures 41 and 36o-ftheplatemembers 37 Vand 31,v respectively,V and then outward through thedirectingtube 7.
